To all whom timely concern v A.

Be it known that I, 'WILLIAM- Boss., a citizen ofthe United States,Yresiding at St. Paul, in the county of Ramsey and Statefof Minnesota,have-invented certain newand useful Improvements in Metal Roof-Edgings,of which the following is a specification.'v""` kvk My invention relatesto metaledging for prepared roofing and has for'its' lobject' to provide"a inishi'ng strip to be-.applied to ends of therooiingf and roof andwhich covers .a portion of the rooling andieXtendsdown voverthe edgeofthe rooing and` partof the roof proper, sothat theedge of"the roofingshallV be vprotected "'fromf injury. This not only protectsv the edgeofthe yroofA ing but is particularly advantageous inV that it provides aprojecting portion kwhich nishes the edge of the roofin much the samemanner as is done vwithfshingles, where 'these V areused, thus remedyingthe unattractive ei'ect always presentwhere prepared roofsA Jareemployed andI merely carried "over the edge of the roof. v'Ihe'us'eofsuch a'n'e'dg'-l ing entirely does vaway with the necessity of carryingthe rooting overV thepedge, jwhich may be more'readily appliedbecauseof-this fact. Another objectisfto A make thisledgin'g with aturned-down side so thatgit'iforms `a waterftight jointwith theroo'ngpiin :order Y that the rain and snow will yshedv oli the roofproperly and not creep in between A the roof and the roofing and rot thesame.

and also to raise portionsofthe metal adj acent the nails used forfasteningy the same so that the water willnot tendto'ow into thecavities through which the nails are 1n- Vser-ted and corrode the edgingand nails. A

further object is to provide the edging in strips of standard sectionsin single lengths of such a form that the saine may bereadily puttogether in a straight line or at right angles or bent over the hip ofthe roof, if desired.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof and are particularlypointed out in the claim.

As shown in Figs. 5 and 6 the protrusions 18 are arranged intwo rows 21 vand 22 of which row 22 is adjacent the edge 13 and row 21-adjacent the lap 17. The nails in row 22 serve to clamp the edge 13against and into the rooing 11 so that a tight joint is secured whichwill cause the edging to shed water. It will be noted that there aremore nails used in row 22 than in row 21 for this reason. The portions16 of the edging strips lie Hat against the edge of the roofing 11 andthe roof 10, as shown inV Fig. 2', and so prevent water from enteringbetween the two and rotting the same. Portion 14 and the back 12 formanornamental trimming for the roof as well as a protective device, as willbecome evident from Fig. l.

each end of the strip, portions 15 are cut 01T obliquely at 23, andportions 16 and 17 are cut off at right angles toth'e stripfproper at24. The removal of portions of the metal-in this manner permit the endsofV respective strips to be inserted into each other either atright-'angles or in a straight line; ascle'airly shown in Fig. 5. EdgesVA24-inf =the-straight f edge 24 of one strip butts up against theportion-lofthe next strip, and the body 12 of saiclfirst strip isinserted between the lap 17 and the body 12 of the second strip. Thewhole length'iofthe 'edging is of uniform construction and, due to thethinness of the metal employed,-the same readilyfbendssand is sprung outto permit of the joints asdescribed.' i

The hip of the roof is covered with a single angular stripl ofy metal 25tightly fitting the roof hipyas'clearly' shown. in Fig.l 3. 'The edgingcan be Aadapted to the hip in several ways. In Fig. 4 the same is shownas bent at 26 to conform to the angleo-f the hip and is continuous onboth sides. In this' casethe hip strip 25 may be placed over, or underthe edging as desired.4 In Fig. 9 is shownV a sect ond-method ofadapting the tedging to the hip. In this case theV edging is eut andfitted Y together at 27, which-of course necessitates the placing of thehip strip` 25 over the edgingstrips. t i I f Fig. 7 shows amodification-"of thesection .shown inFig. 2. y' A singlefrowbf protru-Copies of thisv patent" mayh'be bt'ainedfo'r vv'e'eents eac in Figs.2and 7.

to meetthe bbdy 29 at 31. A beading is thus formed. `The main differenceis, however,

theabsence of the lap 17 found on the strucl'ture shown in Fig. 2, whichmakes it somewhat' zcheaper to construct than thother.

g-The'modiieation shown in Fig. 8 is quite similar to that shown in Fig.7. Here Va body 32 is provided with a-rol'fl'ed portion 33 offcylindrical vstructure' to constitute a beading.- The fo'r-Inationfofthis portion'y Sii-takes placein a single .opera-tion,- as contrastedwith `the similar portions ofthe strips shown I claim: Y 1 t An edgingfor roofing comprising a sheet metal strip-having ya flat top portionand a turned-overportionat the lower edge', the flat portionbeing.adapted to engage the roofingand to be'secured' to the roof and theturned over portion comprising a lportion formed parallelk with the topportion and spaced therefrom, and a right-angled flange Y turned up fromsaid parallel portion and adapted to fit closely against the roof'edge,the ends of said parallel portion beinginwardly miteredand the endsofthe 'rightangled portion being cutoff1 straight at the terminationofthe mitered cuts to permit the edging strips to be joined either inalinement or at right angles 'to one another.
